Mark Hamill -- who hasn't been idle since the original Star Wars trilogy, by the way -- seems to have had a banner year. He appeared in the movie Kingsman: The Secret Service not as himself (to be truer to the comic book source material), but as a new character called James Arnold.
He also reprised his role of the Trickster on The Flash TV show, and -- as shown on the internet (and in the movie, of course) -- he has once again stepped into the shoes of Luke Skywalker in the latest episode in the new Star Wars movie, Star Wars: The Force Awakens. Though he may be in there only to pass the torch, it's good to see him in the franchise again.
Hamill, of course, is a genuine fan of many things geeky so it pleases me to see him active in two of my favorite fandom arenas (DC Comics and Star Wars).
Time to fire up my old Batman: The Animated Series vids to get a good helping of his other spectacular role, as the voice of the Joker.
